Thanks Andrew,

I did that and it seems to be built correctly. I have a libGLESv2.dll and it has 
a dependency on D3D9.dll. My test app still doesn't work though. That appears to 
be due to this
https://bugreports.qt-project.org/browse/QTBUG-29925
but the error message is slightly different. I am trying to run it on Windows 7 
in a Virtualbox VM.

For completeness' sake here are the details.

The app is a PyQt5 app packaged with PyInstaller (code snippets below)

I get this error:

file://path/to/hello.qml:1
:1: module "QtQuick" is not installed
      import QtQuick 2.0
      ^
class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(void):
Could not initialize egl display: error 12289

QtQuick: failed to create OpenGL context

hello.qml:

import QtQuick 2.0

Rectangle {
     width: 360
     height: 360
     Text {
         anchors.centerIn: parent
         text: "Hello World"
     }
     MouseArea {
         anchors.fill: parent
         onClicked: {
             Qt.quit();
         }
     }
}

hello.py:
...
def main():
     global a
     a = QApplication(sys.argv)

     q = QQuickView()
     if getattr(sys, 'frozen', None):
         basedir = sys._MEIPASS
     else:
         basedir = os.path.dirname(__file__)

     q.setSource(QUrl.fromLocalFile(os.path.join(basedir, 'hello.qml')))
     q.engine().quit.connect(a.quit)
     q.show()
     a.exec_()
